Have you ever wanted to optimize your body to its full potential, while still being relatively lazy?

Who hasn't!

An interesting list has popped up over at mohammadi.ca detailing 18 fascinating ways that we can take advantage of a variety of situations, simply by knowing how to tweak our bodies just the right way, at just the right time.

Here's a few excerpts:

2. Experience supersonic hearing!

If you're stuck chatting up a mumbler at a cocktail party, lean in with your right ear. It's better than your left at following the rapid rhythms of speech, according to researchers at the UCLA David Geffen School of Medicine. If, on the other hand, you're trying to identify that song playing softly in the elevator, turn your left ear toward the sound. The left ear is better at picking up music tones.

7. Cure your toothache without opening your mouth!

Just rub ice on the back of your hand, on the V-shaped webbed area between your thumb and index finger. A Canadian study found that this technique reduces toothache pain by as much as 50 percent compared with using no ice. The nerve pathways at the base of that V stimulate an area of the brain that blocks pain signals from the face and hands.

17. Breathe underwater!

If you're dying to retrieve that quarter from the bottom of the pool, take several short breaths first -- essentially, hyperventilate. When you're underwater, it's not a lack of oxygen that makes you desperate for a breath; it's the buildup of carbon dioxide, which makes your blood acidic, which signals your brain that somethin' ain't right. "When you hyperventilate, the influx of oxygen lowers blood acidity," says Jonathan Armbruster, Ph.D., an associate professor of biology at Auburn University. "This tricks your brain into thinking it has more oxygen." It'll buy you up to 10 seconds.
